这里有新鲜出炉的Bootstrap v3教程,程序狗速度看过来!
Bootstrap Web前端CSS框架
Bootstrap是Twitter推出的一个开源的用于前端开发的工具包。它由Twitter的设计师Mark Otto和Jacob Thornton合作开发,是一个CSS/HTML框架。Bootstrap提供了优雅的HTML和CSS规范,它即是由动态CSS语言Less写成。Bootstrap一经推出后颇受欢迎,一直是GitHub上的热门开源项目,包括NASA的MSNBC(微软全国广播公司)的Breaking News都使用了该项目。
距离上次发布 4.0 的最后一个 alpha 版已经过去了 7 个月。今天,Bootstrap 4 的首个 Beta 版终于发布了。
该版本取消将 Normalize.css 作为依赖关系,而是 fork 其中的一部分并和 Bootstrap 自家的 Reboot 混合,以获得更稳定的标准化方法。还对导航、网格进行了改进以及对 Flexbox 进行一些兼容性的处理。
此外,该版本将 jQuery 和 Popper 移动到了 peerDependencies
,因为它们不是 Bootstrap 每个部分所要求的。往下阅读更多的更新内容。
值得关注的更新:
Dropped Normalize.css as a dependency, forking some of it and remixing it with our own Reboot for a more stable normalization approach.
Update navbar responsive behaviors to be mobile first, use a new class name .navbar-expand
instead of .navbar-toggleable
, remove toggler position modifiers (relies on flex utils now), and fix a handful of bugs.
Stabilize some grid behaviors and update the docs.
Updated the grid to drop push, pull, and offset in favor of new .order-
modifiers and margin utilities.
Renamed tons of variables (see #22414 and #22092) for a more consistent naming scheme.
Removed remaining cursor: pointer
s to restore browser defaults and better indicate actions vs hyperlinks.
Renamed flexbox order
utilities to better match utility naming scheme of .property-value
.
Restored Alpha 5's placement of _custom.scss
in our import order.
Rewrote display and responsive utilities to de-dupe a bunch of functionality.
Removed Gruntfile and docs from package manager builds.
Overhauled our color system with new Sass maps, variables, classes, and component variants.
Updated browser support to bring ranges up to more recent versions.
Added a bash script for linting unused variables.
Moved jQuery and Popper to peerDependencies
as they're not requirements for every part of Bootstrap.
